### Question: What are the symptoms of Ectodermal dysplasia?
### Response: People with ectodermal dysplasia may not sweat or may have decreased sweating because of a lack of sweat glands.
Children with the disease may have difficulty controlling fevers. Mild illness can produce extremely high fevers, because the skin cannot sweat and control temperature properly.
Affected adults are unable to tolerate a warm environment and need special measures to keep a normal body temperature.
Other symptoms include:
Abnormal nails Abnormal or missing teeth Absent or decreased tears Decreased skin color (pigment) Heat intolerance Inability to sweat Large forehead Lower than normal number of teeth Low nasal bridge Poor hearing Poor temperature regulation Poor vision Thin, sparse hair Thin skin
